Scientific paper

In a study of 36 extragalactic radio sources observed over 7 years with the Green Bank Interferometer at 2.7 GHz and 8.1 GHz, Fiedler et al. have detected unusual variations in the light curves of several sources. The most dramatic event, found in the flux record of the quasar 0954+658, showed large modulations at both frequencies. Fiedler et al. argue cogently that these variations are unlikely to be intrinsic to the sources and that refractive scintillation in the interstellar medium is probably responsible. The authors present a detailed interpretation of the event in 0954+658, propose possible sites for the refracting clouds and suggest some future observations.
